The Bulgarian designers claim their all-electric Alieno Arcanum vehicle is "the most powerful hypercar, the world has ever seen."

The top priced model of the 5221hp hypercar will be capable of over 303 mph and is available for pre-order at roughly $1.73 million.

Ahmed Merchev, founder of Alieno, explains: "Alieno Arcanum is an all-electric hypercar from the future with a brutal technical superiority, which is in the basis of the DNA of the brand ALIENO. This our debut model, expressing clearly the mission of ALIENO to create hypercars with alien technologies from the future into the present."

Alieno Arcanum is a two-door, two-seater, with 8880 Nm of torque and a power-to-weight ratio of up to 2.64 hp/kg. It is available in three versions: STR (Street), TRC (Track) and RCE (Race), with the latter suitable for entry into the protoype category of the 24 Hours of Le Mans race.

Ivan Kirov, CTP (Chief Test Pilot) and CSO (Chief Sales Officer) of Alieno says: "Our debut model ALIENO ARCANUM, is definitely the most powerful hypercar, the world has ever seen. Not only it is the most powerful car, but it is robotic and all-electric. This means that it is so much faster in any way, than an equivalent in power, ordinary combustion engine car. This is due to the high efficiency of the electric motors and the innovative ALIENO technologies that we built into the car."

Ivan explains that with so much power available from electric technologies the challenge is actually to keep the power restrained, comfortable to drive and, importantly, safe.

He says: "The challenge comes from the fact, that we not only had to do something extraordinary, in terms of the power of the car, which was of course very difficult technically in the first place, but we also and mainly had to make it usable. What I mean by that is, that we had to utilize this power, in such a way, that it could be used by the car and the driver. What would be the use of a car, which has so much power, but you can use only a fraction of it. Or if it would be too dangerous or difficult to drive."

Alieno says their pre-order is now open and each car will be assembled by hand in Bulgaria. Prices start from $867,000 and delivery time varies from 18 to 30 months, depending on the chosen modification (STR, TRC or RCE) and other options chosen by the customer.
